IMPROVEMENT INTHE CONSTRUCTION or SHEET-METAL BUGKETS.

TO ALL WHOM IT MAY CONCERN:

'Be it known that I, JAMES FALLOWS, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in the Manufacture of Sheet-Metal Buckets and other vessels having flared or flanged bases;-and I do hereby declare'that the following is a full, clear, and exact descriptionof the construction of the same, reference being had to the accompanying drawings, making a part of this-specification, in which Figure 1 is a side elevation of a coal-bucket or bed.

Figure 2, a vertical diametral section of the base of the same; and

Figures 3 and 4, horizontal sections, respectively, on thedotted lines x and y of fig. 1-

Like letters of reference indicating the same parts when in the different figures.

The object of my improvement is to lessen the cost of manufacturing sheet-metal vessels requiring flanged or flared bases, and at the same time to increase the strength and rigidity of their bodies.

My invention consists in producing the flanged or flared base of a coal-bucket, or other shect-metal vessel requiring a flgired'hase, by corrugating the plates of which the body of the vessel is formed, so as to cause the lower portions of the'same to be thrown obliquely outward by the operation, in such a manner as to produce the flarcdbase required, substantially as hereinafter described and set forth.

K Referring to the drawings, A B is the body of a sheet-metal coal-bucket, as improved, and CD the flared. base of the same. The body A B and the base 0 D are both formed together of the same piece or pieces of sheet metal, the'fiaring form being given by malaing the corrugations or wrinkles a b in that portion of the said plate or plates which goes to form the body of the'vessel, (see fi 1.) Thecorrugations a b, figs. 1 and 3, are produced by compressing the sheets of metal which areto form the vessel between appropriate dies constructed for the purpose, and so also as to keep the flaring portion}? D even and uniform or free from wrinkles, (see figs. 1 and 4.) The corrugated sheets of metal are then united together at their side edges in the usual well-known manner'of uniting sheet-metal plates, there being two or three sheets generally required to complete the circumference of the vessel. The bottom plate e is then attached by overlapping its edge upon the edge of the base, substantially as shown in fig. 2, and the upper edge of the vessel then wired, and finally finished by attaching the bailf, if a bucket, as heretofore.

It will be seen that the producing of the corrugations a b will necessarily contract the sheet metal at the parts, in a direction across them, and thus cause the plain part O D below them to flare outward, and that the latter will be readily curved, by the closing of the dies, into a uniformand even shape, substantially as shown in fig. 1, whilst the corrugations a b will greatly stiflen the body B, and that therefore the necessity of riveting a flanged or flared base to a separately formed body, as heretofore, is avoided, and a stronger and better articleproduced from the same material, and at less expense.

Having thus fully described my improvement, what I claim as new, and desire to secure by Letters Patent, is confined to the following, viz:

I claim producing the flared or flanged base of a shcetmetal vessel requiring sucha base, by corrugating the sheet metal of the body of the vessel, substantially as described and set forth.'
